Safety Instructions
Ergonomics
Avoid dazzle, refl ections and a light-dark contrast that is too strong in
order to protect your eyes.
The all in one PC should never be placed next to a window because this is the
brightest part of the room in daylight. This brightness can make it more diffi cult for
the eyes to adjust to the darker display. The all in one PC should always be positioned
so that the direction of vision is parallel to the window front.
Setting up the all in one PC with your back to the window is incorrect as refl ections
from the bright window on the screen will then be unavoidable. A position looking
onto the window is also incorrect as the contrast between the dark screen and the
bright daylight can cause problems for the eyes to adjust and result in problems.
The parallel line of vision should also be maintained in relation to artifi cial lighting
equipment.
In other words, the same criteria and principles apply where the workspace is
illuminated with artifi cial light. Where space restrictions make it impossible to set up
the screen as described, then correct positioning (rotating, tilting) of the all in one PC/
screen can prevent dazzling, refl ections and excessive bright-dark contrast, etc. In
many cases, an improvement can also be achieved by using slats or vertical blinds on
the windows, partition walls or by changing the artifi cial lighting equipment.
Take regular breaks when working at your all in one PC to prevent
tenseness and fatigue.
Sitting for a long time without changing position can be uncomfortable. Correct
posture is very important for minimising the risks of physical problems or damage.
